Leareth describes the parts he remembers; even those are sometimes a bit hazy. Their first meeting, the conversation when he was injured and she was Healing him; he remembers his panicked exit from the bed, and her shouting at him about it, but not why he was trying to get up. He remembers taking her to one of his records stashes, trying to explain his past, her very understandable disbelief. He remembers telling her about Urtho, and her telling Vanyel in turn.
...He also has a few memories that are, well, not exactly of conversations, and feel very awkward now that he's in the body of a thirteen-year-old who does not, apparently, have much of a libido yet.
